c15b1d20cd Minor optimization of unloading prevention patch. 
References to unique symbols from copy relocations can only come
from executables which cannot be unloaded anyway.  Optimize the
code to set the unload flag a bit.

077e7700b3 Some more fixes for the unique symbol handling. 
The hash value can be zero, so we need a different test for empty
slots.  And unify the way we prevent a DSO from being unloaded.

2b7a8664fa SSE4.2 strstr/strcasestr for x86-64. 
This patch implements SSE4.2 strstr/strcasestr, using Knuth-Morris-Pratt
string searching algorithm.

8a4494506d Check generated locale for non-ASCII 8-bit characters with case conversion. 
If a locale does not have 8-bit characters with case conversion which
are different from the ASCII conversion (±0x20) then we can perform
some optimizations.  These will follow later.

515a8908ce Make x86-64 pthread_cond_timedwait more robust. 
It just happens that __pthread_enable_asynccancel doesn't modify the $rdi
register.  But this isn't guaranteed.  Hence we reload the register after
the calls.

1c0ab5bd34 Handle overly large answer buffers in resolver. 
In EDNS0 records the maximum result size is transmitted in a 16
bit value.  Large buffer sizes were handled incorrectly by using
only the low 16 bits.  Fix this by limiting the size to 0xffff.

137028b4d7 Fix lock handling in memory hander of nscd. 
The commit 20e498bd removes the pthread_mutex_rdlock() calls, but not the
corresponding pthread_mutex_unlock() calls. Also, the database lock is never
unlocked in one branch of the mempool_alloc() if.

I think unreproducible random assert(dh->usable) crashes in prune_cache() were
caused by this. But an easy way to make nscd threads hang with the broken
locking was.

50158f9552 Use correct release semantic in list update. 
nscd uses lockfree lists and we need to ensure the correct release
semantics is used when adding to the list.

bec466d922 Fix race in corruption check. 
With atomic fastbins the checks performed can race with concurrent
modifications of the arena.  If we detect a problem re-do the test
after getting the lock.

bea0ac1d87 Use rel semantics of cas instead of acq semantics with full barrier before it in _int_free 
The following patch fixes catomic_compare_and_exchange_*_rel definitions
(which were never used and weren't correct) and uses
catomic_compare_and_exchange_val_rel in _int_free.  Comparing to the
pre-2009-07-02 --enable-experimental-malloc state the generated code should
be identical on all arches other than ppc/ppc64 and on ppc/ppc64 should use
lwsync instead of isync barrier.

d7bd7a8ae8 Secure AVX changes for auditing code. 
The original AVX patch used a function pointer to handle the difference
between machines with and without AVX support.  This is insecure.  A
well-placed memory exploit could lead to redirection of the execution.
Using a variable and several tests is a bit slower but cannot be
exploited in this way.
